325/30R20 Tire Width

Tire width is the measurement of the tire's cross-section at its widest point. 325/30R20 tire has a width of 325 millimeters or 12.8 inches.

Tires with section width of 325 millimeters come equipped on a variety of pickup trucks and sport utility vehicles.

Tire width of 325 millimeters falls under extra wide category. For trucks and SUVs, extra wide tires offer enhanced stability and load-carrying capacity. For high-end sports cars and supercars they offer maximum traction and performance at high speeds.

Tire width plays a pivotal role in determining a vehicle's handling, safety, and efficiency. It is crucial to consider the compatibility of tire width with the vehicle's design and the manufacturer's specifications to maintain optimal functionality and ensure safety.

325/30R20 Aspect Ratio

Tire aspect ratio represents the height of the tire's sidewall as a percentage of its width. 325/30R20 tire size has an aspect ratio of 30%.

Tires with an aspect ratio of 30 fall into a category often referred to as ultra-low profile tires. These are characterized by very short sidewalls and are typically used on modern supercars and high-end sports models.

The primary advantage of an ultra-low aspect ratio is improved handling and responsiveness. The shorter sidewall makes the tire stiffer, which reduces sidewall flexing during cornering. This stiffness allows for more precise steering response and improved stability at high speeds, which is crucial for performance-oriented driving.

It's important to note that while ultra-low profile tires offer certain performance benefits, they also come with trade-offs. The ride quality tends to be much firmer, which can be less comfortable on rough roads. Additionally, the reduced sidewall height offers less protection for the wheel, making them more susceptible to damage from potholes or curbs. Due to these characteristics, such tires are best suited for smooth surfaces and performance driving conditions. Vehicle owners considering tires with such low aspect ratios should weigh these factors carefully and ensure that their choice aligns with their driving needs and conditions.

325/30R20 Rim Diameter

Rim diameter refers to the diameter of the wheel on which the tire is mounted, commonly measured in inches. 325/30R20 tire can be mounted on 20-inch wheels. The rim diameter directly correlates with the overall diameter of the tire and affects various aspects of vehicle performance and aesthetics.

Tires with rim diameter of 20 inches are equipped on a select crossover, minivan, passenger car, pickup truck, sport utility vehicle and van models.

20-inch rims are often used on high-end SUVs, light trucks, or high-performance sports cars. 20-inch rims are usually chosen for aesthetic reasons, or to accommodate larger, more robust tires needed for off-road or heavy-load conditions.

When selecting a rim diameter, it's crucial to consider the vehicle's design specifications, as altering the rim size can affect the speedometer and odometer calibration, vehicle handling, suspension geometry, and brake clearance.

325/30R20 Tire Diameter / Height

Tire diameter represens the total height of a tire, including the rim, when it is fully inflated and not under load. 325/30R20 tire height is 704 millimeters or 27.7 inches.

Tire height affects the clearance between the tire and the vehicle's body or chassis, influences the vehicle's ground clearance, and can impact the accuracy of the vehicle's speedometer and odometer.

For standard passenger cars, tire diameters typically range from about 24 to 30 inches. This includes sedans, hatchbacks, small SUVs, and minivans. Light trucks and larger SUVs might have tires on the higher end of this range or slightly above, often between 29 to 33 inches. Sports cars and high-performance vehicles may have similar diameter ranges as standard passenger cars, but they often feature wider tires with a lower aspect ratio, which can slightly affect the overall diameter. The range for these vehicles is typically between 24 to 30 inches, focusing more on width and profile for performance. Off-road vehicles, including larger SUVs, trucks, and specialized vehicles, often have larger tire diameters to handle rough terrain better. The diameters for these vehicles can range from about 31 to 40 inches or more, depending on the level of off-road capability and customization.

325/30R20 Sidewall Height

Tire sidewall height, determined by the aspect ratio of a tire, represents the height of the tire's sidewall, measured from the edge of the rim to the top of the tread. 325/30R20 tire sidewall is 98 millimeters or 3.9 inches tall.

Sidewall height affects the tire's ability to dissipate heat and impacts its load-bearing capacity. It also plays a role in aesthetic appeal for many drivers, influencing the overall look of the vehicle.

Tires with a sidewall height of 3.9" are considered low profile. Lower sidewall height, commonly seen in performance tires, generally enhances handling and steering response by reducing flex and deformation under stress. This results in a firmer ride quality and increased stability at higher speeds, making them suitable for sports and performance vehicles.

3.9"

325/30R20 Circumference

Tire circumference is the total distance around the outer edge of the tire. 325/30R20 tire has a circumference of 2211 millimeters or 87 inches.

Tires with a circumference of 87 inches are common on mid-size cars, minivans and SUVs. These tires strike a balance between fuel efficiency and comfort, offering a smoother ride than smaller tires while maintaining reasonable handling and efficiency.

Tire circumference directly influences the speedometer and odometer readings of a vehicle. Mismatched tire circumferences, especially on the same axle, can lead to uneven wear, handling issues, and even mechanical damage, particularly in all-wheel or four-wheel-drive vehicles.

325/30R20 Revolutions

Tire revolutions metric reflects the number of times a tire rotates over a fixed distance. This figure is inherently tied to the tire's circumference - the larger the circumference, the fewer the revolutions needed to cover a mile, and vice versa. 325/30R20 tire makes 452 revolutions per kilometer or 728 revolutions per mile.

Number of the revolutions a tire makes affects greatly vehicle's performance, from speed and distance measurement accuracy to handling, fuel efficiency, and wear and tear.
